NBT.B.6 Division

Edit 0 30 …

Number & Operations in Base Ten - Perform operations with multi-digit whole numbers and with decimals to hundredths.


CCSS.Math.Content.5.NBT.B.6

Standards and Progression Explanations:
1. Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on:
  • place value,
  • the properties of operations,
  • and/or the relationship between multiplication and division.

2. Illustrate and explain the calculation by using
  • equations,
  • rectangular arrays,
  • and/or area models.

**Progression Document for NBT** - this takes the general standards down to a specifics level on what needs to be taught and what models are required at what grade. This is essential so that the students have the tools they will need for the more advanced topics.

Georgia's Enduring Understandings:
  • There are two common situations where division may be used: fair sharing (given the total amount and the number of equal groups, determine how many/much in each group) and measurement (given the total amount and the amount in a group, determine how many groups of the same size can be created).
  • Some division situations will produce a remainder, but the remainder will always be less than the divisor. If the remainder is greater than the divisor, that means at least one more can be given to each group (fair sharing) or at least one more group of the given size (the dividend) may be created.
  • The dividend, divisor, quotient, and remainder are related in the following manner: dividend = divisor x quotient + remainder.
  • The quotient remains unchanged when both the dividend and the divisor are multiplied or divided by the same number.
  • The properties of multiplication and division help us solve computation problems easily and provide reasoning for choices we make in problem solving.

Georgia Essential Questions:
  • How can estimating help us when solving division problems?
  • What strategies can we use to efficiently solve division problems?
